' NON-SKID DEVICE.

' tion of the invention. such as will enableothers skilled in the art to which it pertains to make and use the same.

This invention relates to improvements in non-skid attachments for automobile tires.

The object of this invention is to provide a device or attachment of this character which will be very effective in preventing tires from slipping or skidding on slippery pavements and which will also serve as a mud-hook on wet or soft ground.

A further object of my invention is to provide a device for the above mentioned purposes which will be cheap to manufacture and which can be easilyplaccd on or taken ofi of a tire.

lily invention-therefore consists of the features if construction and combination of parts. hereinafter described in the specification. particularly pointed out in the.

claim and illustrated in the accompanying i'lrawings.

Referring to the accompanying drawings. Figure 1 shows a portion of an automobile tire with one of my non-skid devices applied thereto. Fig. 2 is a side viewof the same and Fig. 3 is an end view of the same- Again referring to'the drawings 2 represents the telly of a wheel. 3 represents the rim and 4 the tire. Each. of my non-skid devices is a unit comprising four distinctively formed members flexibly coi-inect-ed together. The members are arranged in pairs and the members forming each pair are butted transversely but the pairs are spaced longitudinally a predetermined dis-- tance apart. Each member comprises a rectangular plate, 7, curved to conform to the circumferential and transi 'erse curvature of the tile. On the face of each plate are, formed two rows of lugs. 8, which run transversely of the tread of the tire. The sides of these lugs. 8 are beveled so that the lugs have flat or blunt points. As is clearly shown in Fig. 1 of the drawing, the beveled portions of the lugs of the entire series of Specification of Letters Patent. Paton fed X0 29 1921, Application filed January 27, 1920.

disposed. The adjacent edges of the plates 7, ol' the members.which are arranged in pairs are brought close together with the i'ows of lugs H in alinenient and the adiacent lugs on the two plates are flexibly connected by means of coupling members orrings 9. liach plate of one pair of plates isconnected to the opposite. plate of the other pair'- of plates by a short length of chain. ll). the ends of which are secured to cars or projections 11 formed on the plates.

llach pair of plates is provided with independent means for securing said plates to the tire comprising chain sections shown at I4 and 17 Ilach chain section is secured to the outer corner of a plate. preferably to one lug thereon and'is then carried around the tire and felly and the ends of the chain sections are united together by means of a book 17. on one section which engagesa link on the other section.

liy the arrangement described T am able to provide a very clliciient non-skid device. The lugs and plates afl'ord ample means for engagement with the surface traveled over and my method of flexibly connecting the .nicmbers ol' the device together and also to the the permit the freedom of movement necessary in a device of this character.

What l olaim is:-

A noii-skid device comprising a single u-nit consisting of four distinctively formed members. each member of said-unit being a rcctaugular plate curved to conform to the curvature of a tire. each plate having a double row of lugs extending transversely thereof. the entire series of lugs of said unit liaving radial t'aces on one side thereof, and. beveled. faces upon the opposite side of said series, means flexibly connecting said m bei's transversely and longitudinally. and. flexible elements attached to the lugs at the respective outer corners of said members for connecting the unit to the tire.

In testimony whereof. I sign the foregoing specification in the presence of two witnesses.
